Folks - Given the wealth of DIY knowledge here, thought I'd see if I could ask some advice on a small masonry repair job.
I have a front porch which is a concrete slab with bluestone on top and, of course, also as a veneer facing outwards. A few of the pieces facing outwards have fallen off, so I'd like to paste them back on.
The mortar holding these pieces on was applied pretty thickly, apparently used as a spacer to get the right amount of overhang above them. It was applied about an inch thick. This inch-thick mortar has come off with one of the pieces, held to the concrete face on another spot, and on the third bluestone piece, the mortar fell off completely.
My questions: Since the thick mortar spaces the bluestone out from the concrete at the right distance to line up with all the other bluestone pieces, can I just use some sort of outdoor epoxy to put back the two pieces which have adherent mortar? The mortar seems to be very well attached to, respectively,the bluestone and the concrete slab face.
Or, do I need to remove the mortar with a cold chisel, and redo the thick layer -which seems way thicker than one is supposed to use in a mortar mix?
Lastly, is there any special mortar mix I need to use to make such a thick layer? Or is that thickness ok for regular quickcrete mortar mix?
In the first pic you can see the pieces of detached bluestone, with the piece of (thick) detached mortar in front, and the mortar still attached in the rear.
Help and thoughts appreciated; I'd like to just do this repair once....
